A Flood Watch has been issued for the North Bay-Mattawa watershed and Watershed Conditions Statement – Water Safety has been issued for the Lake Nipissing Shoreline in North Bay and Callander and the lower reaches of the Mattawa River in Mattawa, according to the North Bay-Mattawa Conservation Authority (NBMCA).
Water levels on local creeks and rivers, including Chippewa Creek, La Vase River, and Wasi River have increased in response to the weekend’s rain and snowmelt. Water Levels on Lake Nipissing and in Mattawa are normal and well below flood thresholds. Changing water levels, increased runoff and warm temperatures will impact ice stability. Flooding is not anticipated along the Lake Nipissing Shoreline nor in Mattawa.
“Recent weather conditions have triggered significant snowmelt and increases in local water levels,” stated Angela Mills, NBMCA Flood Duty Officer. “With warm temperatures and rain over the next few days, water levels and flows are expected to increase further. Localized flooding is possible in low-lying and poorly drained areas.”
The public is encouraged to keep children and pets away from watercourses and shorelines. Area residents and visitors, especially those in low-lying areas, are encouraged to monitor the conditions as they develop and take proper precautions during times of high flows. If you have a flood emergency, please contact your municipality. If you live in an unincorporated township, please contact the Ministry of Natural Resources and Forestry – North Bay District.
As part of the NBMCA Flood Forecasting and Warning Program, staff will continue to monitor weather and watershed conditions and update this message if needed based on the changing weather/streamflow conditions. Staff remain in contact with municipalities and other partners as required.
The general public is advised of these messages through the www.nbmca.ca website with the flood status icon and a link to information about current conditions. NBMCA also circulates these messages to local media and social media, posting on X (@theNBMCA), Facebook (@theNBMCA) and Instagram (nbmcainfo).
This message will be in effect until Friday, March 21, 2025, at 12:00 PM EDT. COMPLETE BULLETIN
